I'm also having this issue - but only with "high action" in raids and instances (WRotation).
I've tried everything suggested so far (slimdx, framework, no dx, no framelock), but still it happens occasionally.
I'm running a Win 10 system with 16GB RAM, a GeForce GTX 1070 and a decent CPU (Xeon 1231v3). I'm also closing all other programs apart from Teamspeak since this is needed when raiding.
The log file just does not reveal anything obvious - it logs the rotation and suddenly (when WOW freezes) it pops the above error.
I would appreciate any tips or hints for testing to overcome this problem.
I like WRobot very much, but to be honest, with this sort of problem it's becoming more or less useless for me...
Thanks in advance for assisting me !
